Enhanced visibility of graphene: effect of one-dimensional photonic crystal (2007)
Chang, Kai, Liu, J. T., Dai, N., Xia, J. B.
We investigate theoretically the light reflectance of a graphene layer prepared on the top of one-dimensional Si/SiO2 photonic crystal (1DPC). It is shown that the visibility of the graphene layers...

The behavior of vortex matter in $\mathrm{Bi_{2}Sr_{2}CaCu_{2}O_{8}}$ in the presence of a low concentration of tilted columnar defects (CDs) was studied using magneto-optical measurements and...

Variant N=(1,1) Supergravity and (Minkowski)_4 x S^2 Vacua (2004)
Kerimo, J., Liu, J. T., Lu, H., Pope, C. N.
We construct the fermionic sector and supersymmetry transformation rules of a variant N=(1,1) supergravity theory obtained by generalized Kaluza-Klein reduction from seven dimensions. We show that...
Supersymmetry and Gravitational Quadrupoles (1999)
Giannakis, I, Liu, J T, Porrati, Massimo
We derive model independent, non-perturbative supersymmetric sum rules for the gravitational quadrupole moments of arbitrary-spin particles in any N=1 supersymmetric theory. These sum rules select a...
Massive Higher Spin States in String Theory and the Principle of Equivalence (1998)
Giannakis, I, Liu, J T, Porrati, Massimo
In this paper we study three point functions of the Type II superstring involving one graviton and two massive states, focusing in particular on the spin-7/2 fermions at the first mass level....
U-branes and $T^3$ fibrations (1997)
We describe eight-dimensional vacuum configurations with varying moduli consistent with the U-duality group $SL(2,Z) \times SL(3,Z)$. Focusing on the latter less-well understood SL(3,Z) properties,...
Dipole Moments of Black Holes and String States (1996)
Duff, M. J., Liu, J. T., Rahmfeld, J.
As a further test of the conjectured equivalence of string states and extremal black holes, we compute the dipole moments of black holes with arbitrary spin and superspin in D=4,N=4 supergravity...
Integrabilities of the long range t-J model of twisted boundary condition (1996)
The integrability of the one-dimensional long range supersymmetric t-J model has previously been established for both open systems and those closed by periodic boundary conditions through explicit...
The 1/r2 t-J model in a magnetic field (1996)
We study the one-dimensional supersymmetric t-J model with 1/r2 interaction threaded by magnetic flux. Because of the long range interaction, the effect of this flux leads to a modification of the...
The effect of new physics on R_b = \Gamma(Z->b bbar) / \Gamma(Z->hadrons) (1994)
Motivated by the $\sim 2\sigma$ discrepancy between the experimental value for $R_b$ and the theoretical prediction of the Standard Model, we examine the effect of new physics on the...
